Would You Have Held McKesson Stock All The Way Up?

An investor who put $10,000 into McKesson Corporation (MCK) stock ten years ago would hold about $62,300 today, before dividends. That same money would have grown to about $35,900 in the S&P 500. Holding the drug distributor looks simple in hindsight, but it was not. So, how many times do you think the stock fell 20% or more along the way.
